瓦斯抽采泵站无人值守系统气体测量技术改造

Transformation of Gas Measurement Technology for Unattended System in Gas Extraction Pumping Station

采用热导型甲烷传感器和涡街流量计测量气体浓度和流速,测量精度和可靠性较低。为了解决上述问题,将红外型甲烷传感器和V锥流量计应用于地面瓦斯抽采泵站气体监测,并讨论了相关的安装和使用注意事项。

To solve the problem of low measurement accuracy and reliability when using thermal conductivity methane sensors and vortex flow meters to measure gas concentration and flow rate,the article proposes to apply infrared methane sensors and Vcone flow meters to gas monitoring in ground gas extraction pump stations,and discusses relevant installation and usage precautions.
